IMPROVEMENT IN PORTABLE COOKING-STOVES.

Specification forming part of Letters Patent No. 139,760, dated June 10,1873; application filed April 8, 1873.

To all whom it may corcem:

Be it known that I, NATHAN O. BOND, of Fairfax Court-House, in the Stateof Virginia, have invented an Improved Cookin g-.Stove Attachment forSummer Use, of which the following is a specification:

The subject of my invention is asupplemental furnace adapted forapplication to the top of a cooking or other stove or range, a-nd by asimple contrivance to be connected with the stove-pipe for draft. Y

My first improvement consists in constructing the said supplementalstove or furnace with a close bottom, a draft opening independent of themain stove, so that, by closing the doors of the main stove, the entiredraft will be caused to pass through the furnace, and a dischargeflue-collar projecting horizontally, which is adapted to connect withthe pipe of the main stove, and serves the additional purpose ofsteadyin g or supporting the rear part of the furnace. My secondimprovement consists in a detachable connecting flue-collar, constructedand applied as hereinafter described.

In the accompanying drawings, Figure l is a plan of the furnace, showingthe stove-pipe and connecting-collar in section. Fig. 2 is a verticallongitudinal section on the line m x, Fig. l. Fig. 3 is aperspectiveview, showing application of the furnace to the top of a commoncooking-stove.

A may represent the top of a common cooking-stove or range, or a stoveof any kind, and B the vertical line-pipe thereof, applied to a collar,C, on the stovetop, or, by means of an elbow, to a similar collar at theback of the stove, as the case may be. The body of my furnace attachmentmay consistV of a single casting, the front part forming a fire-place,D, of sufficient depth to receive thefuel, and the back a combustion orline-chamber, E, of less depth, the top F being flat. In this top areopenings Gr G for the reception of cookingvessels and covers of commonform. H is a feed-door in front, secured by a latch, I, and employed forthe introduction of fuel. At the rear end the casting is formed with acollar, J, for insertion in a suitable liange or opening formed for itsreception in the stove-pipe B.

In applying the apparatus for the iirst time to a stove whose pipe isnot provided with a flange or openingv for the collar J, I cut such anopening by means of a suitable instrument, and apply thereto a ange forthe reception of collar J by means 0f the following devices: K is ashort tube formed to pass through the opening in the stove-pipe from theinside, and having a flange at its inner end to retain it. L is a tubeof somewhat greater length, iitting over the tube K, and likewiseflanged to bear against the outside of the stovefpipe.

M is a rod passing through corresponding openings in the tubes L K, soas to lock the two securely together. This rod carries a damper, N, ofcommon form. The damper constitutes the means of regulating the draft ofthe furnace as required, and when the furnace is not iu use itserves to.close the opening in the pipe, or affords a ventilator for the pipe. Y

The entire furnace may, of course, be made of sheet-iron, if preferred.

A grate of any suitable construction may be introduced into thelire-place of the furnace for burning coal.

The space O, beneath the rear part, which is shown open in thedrawingsmay be occupied by an oven either permanently connected with thefurnace or detachable; or an oven or warming-closet may be provided bysimply closing the back and one side of the space O and placing a doorat the other side.

I am aware that a supplemental or summer stove has before been made tobe applied to the top of an ordinary stove, taking its draft through themain stove and delivering theproducts of combustion through an ascendingipe. This, therefore, I do not claim.

What I do claim and desire to secure by Letters Patent, is-

1. The summer furnace, constructed substantially as herein described,with a close bottom, independent draft, and horizontal discharge-liuc,for the purposes set forth.

2. The removable pipe-collar, consisting of the flanged tubes J K,combined as described, and secured together by means of a damperrod, M.1
